i Application led September Z8, 1903. Serial No. 174,847. (No model.)

To LZZ whom, it 717,607/ concern/.

Be it known that I, CHARLES E. TUNELIUs,`

' a citizen ofthe United States, residing at Chicago, in the county of Cook 'and State of Illinois, have invented a certain new and useful Improvement in Bottle-Tashing Machines, (Case 1,) of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification. A y

My invention relates to bottle-washing machinery, and has for its object improved and simplified construction of suchv a machine.

Brieiiy speaking, my present invention is an improvement overthe bottle-washing mafv chine invented by me and describedin Letters Patent No. 575,046, grantedtherefor..

Some of the-chief features of this invention comprise improved and simplified construction of the cam mechanism for intermittently rotating the bottle-rack and the application of gearing apparatus whereby all chains and belts are eliminated, making the transmission of power much more direct and efficient.`

1n the accompanying drawings I have shown various Views of the machine and the features of invention thereof. f

Figure 1 is an elevation view of the machine. Fig. 2 is a plan View thereof. Fig. 3 Vis a sectional view taken on line 3 3 of Fig. *2. Fig. 4 shows a detached and detailed view of the cam employed, and Fig. 5 illustrates in detail thedisposition of the brush-spintile-mechanism parts. Fig. 6 is a sectional view taken on line 6 6, Figfl'. Fig. 7 is a plan viewotI the machine, the pan andv everything above it being removed. Fig. 8 is a vertical sectional View taken on line 8 8, Fig. 2. Figs. 9Aand 10 are detail views'showing the construction and operation of a water-controlling valve, and Fig. 11 shows in detail the distributing and rinsing pipe, y s

Like characters of reference refer to like parts throughout the various iigures.

A pan-shaped frame 1 is supported by legsv 2 2, an L-shaped brace member 3 extending upwardly and sidewardly and. terminating in a bearing 4, disposed above the centerl of the pan-frame. A shaft 5 extends upwardly from the pan-frame l and is secured at its upper end in bearing 4 by means of `set-bolts 6 6. A frame 7 has a downwardly-extending hub 8 adapted to sleeve over shaft 5, being `secured thereto in position by means of and over a collar 9. A plurality of vertical square shafts lO lO extend between the spokes 11 11 of the frame and a frame l2, disposed about the bottom of the shaft 5. vided with downwardly-extending hubs 13 13. The bottle-sockets 14 14 consist of an outer rim portion 15, having an annular ridge 16, and an inner socket-shaped portion 17, having a stud 18 extending therefrom and adapted to pass through the hubs 13 to be engaged at its end by a washer 19 and a nut 20. Openings 21 through said socket portion serve to allow water to pass therethrough to the outside of the bottle. A vertical frame 22, havi ing a square bearing 23 at each end thereof,

is provided for each of the square shafts 10 and adapted for vertical travel thereon.

An arm -24 extends sidewardly from said frame 22 and terminates in a pulley-shaped conical socket 22 for receiving the mouth of the bottle, the opening in the center of said socket being in vertical alinement with a corresponding socket secured to the frame 7. A tension-spring 24 is interposed between any point, such as 25, on the sliolable frame 22 and the square .collars 26, which may be verticall y adj usted and secured in any position on said shafts to secure the proper spring-tension for bottles of different lengths, the bottle being placed between said sockets and held in place by said springs, the frame being normally held in place against the collar 26 by the spring. The bottles are thus in position to receive the -brush-spindles 28 28, which communicate at their lower end with a hollow cross-head 29, provided with bearings 430 30, adapted to slidably engage upright rodsv 3l 31, which rods are secured between the pan-frame 1 and lower supporting-bars 32 32. An upper spindle-frame 33 is secured beneath the pan-frame 1, and a lower spindle-frame 34 is secured to the upright rods 31. upper spindle-frame is provided with bearings 35 35, while the lower spindle-frame is provided with bearings 36 36, the brush-spindles passing through these bearings, said` The frame 7 is pro-A This IOO brush-spindles being hollow and terminating in brushes 37 37. through bearings and 36 and are disposed about the brush-spindles. Spiral gears 39 39 are disposed between bearings 35 and 36 and'` are provided with sleeve-hubs 40, which pass through these bearings and about the sleeve -disposed at the lower end of the uprights 31,

and the brushes at the end of their spindles are disposed within the sleeves 38. The sleeves 38 are provided with longitudinal slots 44. whereby frictional engagement is maintained with the brush-spindles, and as the cross-head 29 is raised the sleeves are carried with the brush-spindles until the conical tops of the sleeves engage the lower part of the conical sockets 22', the spindles, however, continuing in their upward travel into the neck of the bottle and carrying their brushes a proper distance to engage the bottom of the bottle.

W ater-under suitable pressure is supplied to the hollow cross-head 29, and thus to the brush-spindles, from a supply-pipe 46 by means of a hose'or pipe 47. One of the spindles 4S is not provided with a brush, but acts as a rinsing-spindle and connects directly and independently with the source of water-supply by means of the hose or pipe 49, the pressure through this rinsing-spindle being preferably maintained as high as possible to insure goed rinsing, while the pressure through the pipe 47 and brush-spindles is reduced by means of a val-ve 50. v

A driving-shaft 51 extends transversely across and below the pan-frame 1 and is provided at its end with a driving-pulley 52 and at intermediate points is provided with similar spiral gears 53 53, adapted to mesh with the similar spiral gears 39, connected with brush-spindles, as best shown in Fig. 3. The spiral gears are disposed in the are of a circle, and this shaft may engage any number of the spindles. However, l prefer to cause the shaft to engage at each side thereof an equal number of gears, and l have shown four spindle's engaged, two on each side of the shaft. The gears being all similar will cause the spindles on opposite sides of the shaft to be rotated in an opposite direction. This disposition of the shaft with respect to the spindles entirely. eliminates end thrust and creeping, as the end thrust and creeping occasioned by the gears on one side of the shaft is en- 'irely counterbalanced by that of the gears at the other side of the shaft. The shaft 51 is also provided witha worm-wheel 55, meshl ing with a worm-gear 56, secured to the bot- Sleeves 38 also pass tom of a vertical cam-shaft 57, which passes through a bearing 53 on the pan-frame and is secured in a vertical position by means of a collar 59. A crank-pin 60, secured to the worm-gear 56, is provided with a balled end 61, adapted for engagement with a socket member 62, secured to a horizontally-extemling connecting-rod 6l A lug 65 is secured at the other end of said rod 6 between adjusting lock-nuts 66 66 and pivotally engages with a lever 67, extending upwardly from a main lever 68, which lever is pivoted in a bearing 69, secured at the lower end of a depending bearing-frame 70. An arm 71, extending from lever 68, carries a weight 72, the other end of said main lever being bifureated, the ends 73 thereof engaging' with connecting-links 74, which connecting-links are pivoted to the hollow cross-head 29. As the drive-wheel 52 now rotates the rod 63 is given a reciprocatory horizontal motion and the main lever 68 caused to raise the cross-head 29 and the spindles connected therewith, the spindles at the same time being rotated by means of the spiral gearing between them and the horizontal shaft 51, the weight 72 helping to maintain the balance of theparts. As the rod 63 pushes lever 67 another lever, 75, pivoted at 75', is engaged to actuate a valve-stein 76 to open a valve 76 to allow a supply of water to the hollow cross-head and spindles. Upon backward travel of the rod 63---tliat is, when the cross-head 29 is lowered to withdraw the brushesthe valve-stem 76 is correspondingly actuated to shut out the supply of water to the spindles, as shown in Fig. 9.

The top of the cam-shaft 57 journals in a bearing 7S,integral with the brace member 3, and a cam 79 is secured to said shaft below said bearing and provided near its periphery with an upwardly-extending stud 80. upon which is journaled a cam-roller 81. A gearwheel S2, which may be integral with the cam 79, is disposed below said cam and concentric therewith. Vertical brushes 83 83 are mounted upon brush-shafts 84 84,e.\'tending` from bearings at the ends of a cross-` frame 35 to bearings 86 86 on the pan-frame. Pinions 88 S8 are secured to said brush-shafts to mesh with the gear-wheel 32 on shaft 57, and directly below said pinions are mounted friction-pulleys 89 89, -adapted to engage with the peripheral iianges on the sockets secured to the cam-rack.

At one side of the stud SO the cam is provided with a gap or groove 90, adapted to engage the hubs 13, extending from the frame 7. As power is now applied to the driving-shaft 5l rotation is transmitted to cam 79 and gearwheel 82 through the medium of the worinwheel, worm-gear, and shaft 57, the brushes being thus continually rotated. The frame 7 is provided with teeth 92 92, and as cam 79 `rotates in the direction of the arrow the cam- IOO llO

roller 81 thereon engages one of these teeth to start rotation of the frame. The gap or groove 90 shortly1 thereafter engages the hub 13, disposed between the engaged tooth and the following tooth. The cam-roller finally leaves the tooth; but the cam-groove still engages the hub 13 to continue the rotation of the frame until this hub also leaves the groove, whereupon the unbroken periphery of thel cam engages between. two of the hubs 13, thus locking the frame 7 in position to prevent rotation thereof until the cam-pulley again comes to a position where the camroller may engage the neXt tooth of the frame 7, whereupon the frame 7 is given another rotary impetus, as before. Each rotation of the cam causes an angular advancement of the frame 7 equal tothe angle between two teeth, and when the rotation of the frame 7 is stopped a bottle is disposed opposite each brush to be cleansed thereby, this cleansing going on until the cam again engages the frame 7, whereupon another bottle is brought into position to be cleaned. Each bottle thus gets two brushings, as when it passes from one brush thel angular advancement of the frame 7 brings it into engagement with the other brush, and upon leaving this brush after its final cleansing the next angular advancement brings it over the rinsing-spindle L18 to be finally rinsed upon the inside.

A hose orvpipe 93 leads from the valve 50 to a distributing-pipe 94E, disposed above the positions occupied by the bottles when washed upon the outside and finally rinsed in the interior, as best shown in Fig. 11i The'water from this distributing-pipe passes from spouts 911', leading from pipe 94, and then throughy the openings 21 in the sockets 17, thus supplying water for the exterior brushes and also supplying water for finally rinsing the outside of the bottle when in position above the rinsing-spindle. The bottles when in engagement with the brushes'SB are given a rotary motion by virtue of engagement of the pulleys 89 with the peripheral fianges 16, the speed of the brush-bristles,however, being very much greater than that of the engaged bottles, whereby a thorough cleansing is assured.

Having thus described the operation of the various parts of the machine, I shall now describe the manner in which these parts cooperate. As power is applied to the drivingshaft 51 the cam-shaft and thel cam thereon are rotated, the cam-roller and the cam-gap engaging a-tooth and hub of the frame 7 to A advance the bottle-rack. The unbrokenpart of the cam-periphery will now engage two of the hubs, thus preventingV the bottle-rackV from further rotation when the `camgap passes out of engagement with the hub. At this moment the connecting-rod 63 is operated tocause the lever 68 to raise the crosshead 29 and the spindles, the water at the same time being admitted to the spindles, the

7, whereupon the same cycle of operations is repeated. While the bottle-rack is locked by the cam the bottles opposite. the vertical brushes are thoroughly washed on the outside and the bottle which has just left a vertical brush is being finally rinsed upon the inside and outside. 4

Changes may readily be made in the various parts of the machine without departing from the spirit and scope of the invention. I do not, therefore, wish to be limited to the precise construction shown; but
